摘要
考虑到岩土工程涉及较多不确定性因素,本文提出岩质边坡可靠度优化设计方法.它包括地质勘探和试验规划的优化决策、地质结构和力学模型的研究,初步设计方案的确定,稳定性的可靠度分析、处理方案的优化决策及工程费用评价和决策分析.此设计方法已应用于龙滩水电站船闸边坡的优化设计,由此推荐的边坡设计方案被工程采用.
A method of optimal design of slope excavation based on reliability analysis is proposed in this paper by considering indeterminate factors in rock engineering.The method deals with the optimal decision of geological prospecting and mechanical property testing scheme,the choice of initial profile, the reliability analysis of stability of slope and the synthetical evaluation of several alternatives, and has been used for optimal design of the excavation of rock slope for the Longtan hydropower project.
